Challenge Mode reappears in Arkham Knight. Originally, all the maps would have Batman on it. As a result of negative backlash, Rocksteady decides to implement Catwoman, Robin, Nightwing, Azrael, Harley Quinn, Red Hood and Batgirl in all maps. The last three are only available from DLC packs. Some of the maps have dual play. The Batmobile maps have three modes: Race, Battle and Hybrid.
